One other tidbit, both the node with enable_wol=1 and the other
nodes show exactly the same thing for "lspci -vv", which is:

02:08.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado]
(rev 78)
        Subsystem: Tyan Computer: Unknown device 2466

        Latency: 80 (2500ns min, 2500ns max), cache line size 10

        Expansion ROM at <unassigned> [disabled] [size=128K]
        Capabilities: [dc] Power Management version 2
                Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA
                Status: D0 PME-Enable- DSel=0 DScale=2 PME-

As I understand this the status should have been D3 (from some
old posts by Donald Becker).  Or maybe it should be in D3 at
shutdown, which of course I can't see because, um, the system
is shutdown!  The node was started with this lilo entry:

        append="devfs=mount acpi=on resume=/dev/hda2 splash=silent
console=tty0 console=ttyS0,38400"

How would does one test that enable_wol is actually being
set during a shutdown initiated by poweroff???
